Cultivation conditions may greatly affect fruit quality, especially in the accumulation of functional metabolites. Blackcurrant fruits (Ribes nigrum L.) have high ascorbic acid (AsA) concentrations. The purpose current study was to investigate influence different shading treatments (full sunlight, and 40% 60% sunlight) on fruits’ maturity, levels firmness, soluble solid, AsA, enzyme activity in...

a breeding hexaploid salt tolerant wheat line (ms-81-14) was produced from crossing of an iranian salt tolerant wheat line (1-66-22) with inia cultivar (from cimmyt) at karaj research station in 1991-92 cropping season. the f1 plants were grown at karaj in 1992-93 cropping season, furthermore f2-f6 populations were evaluated under salinity stress conditions (ecsoil&water; = 8-12 ds/m) in isfaha...

Abstract Developing and applying a novel plant growth–promoting agent (PGPA; micronutrient-amino acid chelated compound developed from autolysis yeast cells) in alleviating salt stress toxicity can be the best alternative option environmentally economically. High-performance liquid chromatography (HPLC) showed that assembled PGPA is rich nucleobases than extract (> 56-fold). This study, as f...

The activities of antioxidant enzymes and levels of antioxidants involved in oxygen detoxification were studied in seedlings of three indica rice (Oryza sativa L.) cultivars, namely Panikekoa and T 1471 that show good capacity for anaerobic seedling establishment (tolerant reaction) and IR 42 which has a poor anaerobic seedling establishment capacity (susceptible reaction). The activities of th...

cadmium (cd), known as a non-essential heavy metal, can cause oxidative stress in plants. in this study, an attempt was carried out to find out whether cd-induced oxidative and microscopic changes could be observed in the early stage of seedling growth. seeds of brassica napus (cvs. zheda 619 and zs 758) were germinated in vitro at 0, 100, 200, 300, and 500 μm cd concentrations in dark for 48 h...
